Abstract

The embodiment of the invention relates to a method for transmitting feedback information, terminal equipment and network equipment. The method comprises the following steps: the terminal equipment receives a trigger signaling, wherein the trigger signaling is used for triggering the terminal equipment to send feedback information; and the terminal equipment determines to send a feedback information codebook by adopting a first feedback mode or a second feedback mode according to the trigger signaling. The first feedback mode is that the feedback information codebook comprises feedback information corresponding to at least one downlink transmission channel indicated by the trigger signaling; the second feedback mode is that the feedback information codebook is a full codebook. According to the method for transmitting the feedback information, the terminal equipment and the network equipment provided by the embodiment of the invention, the downlink transmission efficiency can be ensured.

Description

[0001] This application is a divisional application of a patent application with an application date of February 1, 2019, an application number of 2019800354670, and an invention title of "Method for Transmission of Feedback Information, Terminal Equipment and Network Equipment". technical field [0002] The present application relates to the communication field, and in particular to a method for transmitting feedback information, a terminal device and a network device. Background technique [0003] For the NR-based access to unlicensed spectrum (NR-based Access to Unlicensed Spectrum, NR-U) of version 16 (Rel-16) in the New Radio (NR) system, it supports downlink control signaling (Downlink control information , DCI) introduces a hybrid automatic repeat request (hybrid automatic repeat request, HARQ) feedback timing (HARQ-timing) value of infinity, the value represents the DCI scheduled physical downlink shared channel (Physical Downlink Shared Channel, The transmission tim...
